Abstract
Three manganese coordination polymers [Mn(bimb)2(NCS)2] n (1), [Mn(bimb)2(dca)2] n (2) and [Mn(bimb)2(N3)2] n (3) (bimb = 1,4-bis(imidazol-1-yl)butane, dca = dicyanamide) were synthesized and characterized by X-ray crystallography, IR and thermogravimetric analysis. In 1 and 2, each Mn(II) links two Mn(II) atoms by double bimb ligands and extends to form a one-dimensional double chain structure containing the Mn2(bimb)2 22-member metallocycle. 3 constructs a two-dimensional (4,4) network linked by bimb bridges.
